System for cleaning a sensor/transmitter of a motor vehicle

Abstract

The invention relates to a system for cleaning a sensor/transmitter of a motor vehicle, comprising holes for spraying a first fluid onto the sensor/transmitter an openings for spraying a second fluid onto the sensor/transmitter, the second fluid being different from the first fluid, the cleaning system also comprising a guide body for guiding the first fluid and the second fluid respectively to holes for spraying the first fluid and openings for spraying the second fluid. The guide body of the cleaning system according to the invention comprises a first supply portion, configured to be connected to a source of the second fluid, and a second distribution portion comprising pipes for conveying the second fluid that lead to the openings for spraying it, and a pipe for distributing the first fluid arranged substantially perpendicular to the pipes for conveying the second fluid.

What is claimed is: 
     
       1. A cleaning system for cleaning a motor vehicle sensor/transmitter, comprising:
 a base configured to be secured to a structure of the motor vehicle; 
 a casing configured to cover the base; 
 spray orifices for spraying a first fluid onto the sensor/transmitter and spray openings for spraying a second fluid onto the sensor/transmitter; 
 the second fluid being distinct from the first fluid, wherein the second fluid is a drying fluid; 
 a guide body guiding the first fluid and the second fluid respectively toward the spray orifices of the first-fluid and the spray openings of the second fluid; 
 the guide body including a supply first part configured to be connected to a source of the second fluid; 
 a distribution second part including a plurality of second-fluid conveying ducts opening onto the spray openings of the second-fluid and; 
 a first-fluid distribution duct arranged substantially perpendicular to the second-fluid conveying ducts; 
 
       wherein the casing includes
 a first portion configured to be connected to the source of the second fluid; 
 a second portion configured to form the distribution second part with the base, and 
 the first portion and the second portion making between them a non-zero angle. 
 
     
     
       2. The cleaning system of  claim 1 , wherein a wall of the first-fluid distribution duct is arranged across the spray openings of the second-fluid conveying ducts in a second-fluid spray region. 
     
     
       3. The cleaning system of  claim 1 , wherein the distribution second part of the guide body has a dimension, measured in the longitudinal direction (L) of the cleaning system that differs between an edge connecting with the supply first part and an edge including the spray openings of the second-fluid. 
     
     
       4. The cleaning system of  claim 1 , wherein the openings of the second fluid are uniformly distributed along a direction of elongation of the distribution second part, substantially parallel to a longitudinal direction (L) of the cleaning system. 
     
     
       5. The cleaning system of  claim 1 , wherein the second-fluid conveying ducts are delimited by ribs projecting out from an exterior surface of the base and an interior surface of the casing is configured to be in contact with free ends of respective ribs. 
     
     
       6. The cleaning system of  claim 5 , wherein the ribs delimit the guide body within the distribution second part of the second fluid conveying ducts which are inclined with respect to a longitudinal direction (L) and to a vertical direction (V) of the cleaning system. 
     
     
       7. The cleaning system of  claim 6 , wherein each second-fluid spray opening is delimited by free ends of two ribs along the longitudinal direction (L) of the cleaning system, such that the two ribs are configured to contribute to delimiting a corresponding second-fluid conveying duct. 
     
     
       8. The cleaning system of  claim 5 , wherein the second-fluid conveying ducts are narrowed at each end via which the second fluid is sprayed from them. 
     
     
       9. The cleaning system of  claim 1 , wherein the casing includes a groove to accept a first-fluid distribution pipe in which a plurality of first-fluid spray orifices is arranged. 
     
     
       10. The cleaning system of  claim 1 , wherein the casing includes a first-fluid distribution duct of closed cross section and in which a plurality of first-fluid spray orifices is arranged. 
     
     
       11. A motor vehicle equipped with at least one sensor/transmitter, characterized in that the motor vehicle includes at least one sensor/transmitter-cleaning system of  claim 1  for cleaning the at least one sensor/transmitter.
